Serial ESP STM Communication Problem

Post by modellfan »

Hi everyone,

I’m having an issue with my Zombieverter VCU where I’m unable to install any software updates anymore. Maybe installed an software with a bug before, keeping the STM in boot loop. When I try to do a firmware update, I see a red bar that indicates that the communication between the ESP and the STM isn’t working properly. Initially, it shows no progress, then the bar fills up completely, and then the Wi-Fi seems to reset. But in the end, it doesn’t actually update the firmware. The tricky part is that I’ve sealed the enclosure of the control unit with adhesive, so I can’t easily open it up again to troubleshoot.

My question is: does anyone know of any alternative methods to try and update the software without having to break that seal? Any advice would be greatly appreciated!

Thanks a lot!
